Abstract
An instrumentation amplifier (INA) that includes a first amplifier and a second amplifier coupled to the first amplifier. The first amplifier includes a first transistor. The first amplifier is configured to receive a positive phase signal of a differential signal. The second amplifier includes a second transistor and is configured to receive a negative phase signal of the differential signal. The first and second transistors each include a gate, source, and drain. The first transistor drain is connected to the second transistor drain.
